ASoC: cx2072x: fix integer overflow on unsigned int multiply
In the case where frac_div larger than 96 the result of an unsigned
multiplication overflows an unsigned int. For example, this can
happen when the sample_rate is 192000 and pll_input is 122. Fix
this by casing the first term of the mutiply to a u64. Also remove
the extraneous parentheses around the expression.
Addresses-Coverity: ("Unintentional integer overflow")
Fixes: a497a4363706 ("ASoC: Add support for Conexant CX2072X CODEC")
